Question

solve for x
132 = 1 over 2x + 2 (x - 9)

Answer 1

\[132 =\frac{ 1 }{ 2x + 2(x-9) }\]

Answer 2

\[\frac{ 1 }{ 2 }\]

Answer 3

so how is the equation supposed to look like please clarify :)

Answer 4

its 132 = 1/2x + 2 (x - 9 )

Answer 5

132 = x +2 ( x - 9 )

Answer 6

\[\LARGE{132=\frac{1}{2x}+2(x-9)}\]

Answer 7

Use parentheses when writing your equation. Otherwise there could be a number of different interpretations.\[132 = \frac{1}{2}x + 2(x-9)\] could be written 132=(1/2)x+2(x-9)

Or is it \[132 = \frac{1}{2x} + 2(x-9)\]?

Answer 8

ah ok now I understand better. So first distribute 2 to x - 9
2x - 18
132 = 1/2x + 2x - 18 Then combine like terms which is 1/2x + 2x
132 = 2 1/2x - 18. Then add 18 to both sides.
+18 +18
---------------------
150 = 2 1/2x Then you divide. I got 60! Hope this helped!
